Flotation of Iron Ore: A Brief Review MDPI

Jul 30, 2020 This is why reverse anionic flotation of iron ore using oleic acid or its soaps is usually performed in a strongly alkaline environment (i.e., above pH 11). Fuerstenau and Cummins [28] concluded that, when oleate was used as collector, the suitable pH value was between 11 and 12 in the flotation of quartz.

Froth Flotation of Iron Ores

Jan 02, 2012 With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Froth Flotation of Iron Ores

the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.

The entrainment effect on the performance of iron ore

Oct 01, 2016 The typical feed to a flotation system applied in the cationic reverse flotation of quartz from hematite in the iron ore industry consists of particles in the size range between 10 μm and 300 μm. The slimes fraction (<10 μm) are removed using hydrocyclones prior to flotation and the top size is limited to 5–10% greater than 150 μm.

Abstract. The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter.
